I have just taken the atmos d/v off my sti v5 and bought a rec d/v. Every time i change gear in high boost i get a squeek sound and is this right? I also got a blanking screw with it like the atmo d/v comes with. Can this forge rec dumpvalve become a atmo d/v if the hose is not fitted? Cheers Gary

 

You will get a metallic "ching" sort of noise. Don't blank it off!
